Stochastic volatility and DSGE models

Author

  • Andreasen, Martin M.

Abstract

This paper argues that a specification of stochastic volatility commonly used in DSGE models may not be appropriate, because the level of a process with this specification does not have any moments. We suggest three ways to overcome the problem.
